Endo technique, consists of using a laser beam with a wavelength of 1470 nm emitted through an optical fiber inserted into the subdermal tissue in order to reduce subcutaneous fat and tone the skin through the intense production of collagen.
patients were assisted with just one endo session, where the mandibular and submental regions were
treated. It was by using 200 micron optical fiber, power ranging from 4 to 8 W, in continuous mode. After the procedure, patients were instructed to remain with a bandage on the treated area for 4 days and. Then, after this period they received 4 sessions of manual lymphatic drainage, which was performed once a week.
Results: After treatment and reassessment at the end of 60 days, it was noticed a clear decrease in fat in the cheeks, as well as in the submental region. Also, the skin where the jowl fat was removed underwent intense retraction, as it was seen a decrease in flaccidity and wrinkles.









Lately, the 1470 nm wavelength laser has started to be actively used in surgical procedures. Laser equipment with a wavelength close to 1500 nm has its absorption in water as a predominant characteristic generating specific biological effects. These lasers are water-absorbable or water-specific and are mainly used in urology and for endovenous obliteration of veins . However,authors reported that the 1470 nm diode laser is able to deeply penetrate into tissues due to its high affinity for water and also acting on fat. All due to it is understood that the richer a tissue is in water and fat, the better it will be. the transmission of this kind of laser and the smaller its dispersion [6]. Therefore, using 1470 nm wavelength in non-surgical endo procedures has become very common nowadays.

I. Precise Operation and Minimally Invasive Nature
Due to the small diameter of the optical fiber, the trauma during the surgical procedure is correspondingly reduced. This helps to decrease postoperative bleeding, edema, and ecchymosis, accelerate thepatient's recovery, and lower the surgical risks. It ensures that the energy can accurately act on the target tissue. This contributes to improving the treatment effect, reducing energy loss,and minimizing damage to surrounding tissues.
II. Safety and Comfort
The application of 200 - μm optical fibers in surgeries is generally minimally invasive, which helps to reduce surgical risks and enhance patient safety. At the same time, the small diameter of the optical fiber also reduces the discomfort during the surgical process, improving the patient's comfort level.
III. Strong Adaptability and Flexibility
200 - μm optical fibers can meet the needs of various aesthetic surgeries. Whether it is for facial or body treatments, they can provide effective solutions.This gives optical fibers a broad application prospect in the aesthetic industry. The small diameter and flexibility of the optical fiber enable it to easily adapt to various complex surgical environments.
